Get list of the substring from the string based on the String delimiter

Question

String s = "I like an orange as well as apple but mostly apple. apple, orange are the best fruits.";

String[] delimiter = {"orange", "apple"};

I wanted to split this string like below:

{"I like an ", "orange", " as well as ", "apple", " but mostly ", "apple", ".", "apple", ",", "orange", " are the best fruits."}

In above, I have split the string based on the fruit orange and apple, but both the fruits are also the part of list of substring.

`but mostly apple.` and `" but mostly ", ". "` dont match the requirements — XtremeBaumer, Apr 28 '22 at 14:25
@XtremeBaumer I made a blunder, now I have updated the question. — Kiran Gavhane, Apr 28 '22 at 14:29

Using this answer:

public class Solution {
    public static String[] getTokens(String str, String[] delimeters) {
        if (delimeters.length == 0) {
            return new String[]{str};
        }
        // Create regex: ((?<=delimeter)|(?=delimeter))
        String delimetersConcatenatedWithOr = "(" + String.join(")|(", delimeters) + ")";
        String regex = "((?<=" + delimetersConcatenatedWithOr + ")|(?=" + delimetersConcatenatedWithOr + "))";
        // Split using regex
        return str.split(regex);
    }
    public static void main(String args[]) {
        String str = "I like an orange as well as apple but mostly apple. apple, orange are the best fruits.";
        String[] delimeters = {"apple", "orange"};
        for (String token : getTokens(str, delimeters)) {
            System.out.println("{" + token + "}");
        }
    }
}
